pole-dipole array

pole-dipole array

[′pōl ′dī‚pōl ə‚rā]
(engineering)
An electrode array used in a lateral search conducted during a resistivity or induced polarization survey, or in drill hole logging, in which one current electrode is placed at infinity while another current electrode and two potential electrodes in proximity are moved across the structure to be investigated.

White Rock IP survey A pole-dipole array Induced Polarisation (IP) survey was completed in the White Rock area in July 2009.
Figure 3 shows inverted resistivity images obtained for Wenner, pole-pole, dipole-dipole and pole-dipole arrays (a, b, c & d, respectively) to determine which array best imaged the subsurface cavity; inverted resistivity representing the arrays were compared Figure 3a shows an inverted model obtained using a Wenner array; the image shows that inverted resistivity was underestimated and the model did not resolve the embedded 20 [[ohm].sub.-m] area (subsurface cavity) and thus its image was not a true representation of the subsurface model used.
